The P21A peptide inhibits Rgg‐dependent transcription by SHP144. Decreasing ratios of Δshp144com^P21A and wild type (WT) supernatants were incubated with a pellet of reporter strain P_shp144:: lacZ‐Δshp144, and the Pshp144 driven β‐galactosidase activity was measured (red columns). As a control dilutions of wild type supernatant in Δshp144 supernate were used (black columns). Comparisons are made relative to shp144 transcription levels in culture containing a mixture of WT and Δshp144 supernates. *p < .05 and “n” non‐significant (n = 3).
